Takes ownership of moderately complex components end to end - from design through delivery and support - with limited guidance. Participates in architecture and design discussions, contributes technical input, and helps shape solutions for the team. Identifies and resolves technical issues and dependencies, escalating broader risks appropriately to keep work on track. Supports production systems, troubleshoots issues, and improves reliability, performance, and maintainability of existing code and infrastructure. Participates in code reviews - submitting own work and providing constructive feedback - and helps apply and improve the team's coding standards, tools, and best practices. Provides informal guidance to junior engineers and contributes to onboarding and knowledge sharing. Applies computer science fundamentals - algorithm design, problem solving, complexity analysis, and data structures - and growing experience with Big Data technologies to solve business problems. Uses AI-assisted development tools to work more effectively, applying good judgment to review generated output for correctness, security, and quality. Builds productive working relationships across the team, communicates progress and blockers proactively, disagrees and commits when needed, and demonstrates FINRA's values through in-person and virtual collaboration in furtherance of FINRA's mission of investor protection and market integrity. ## Related Videos - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Leveraging Real time data in FSIs](https://www.wearedevelopers.com/videos/806-leveraging-real-time-data-in-fsis) - [From event streaming to event sourcing 101](https://www.wearedevelopers.com/videos/91-from-event-streaming-to-event-sourcing-101) - [From Messy Queries to Scalable Systems - How Data Engineering actually works](https://www.wearedevelopers.com/videos/100203-from-messy-queries-to-scalable-systems-how-data-engineering-actually-works) - [Tomorrow's cloud data platforms - fully managed database-as-a-service (DBaaS)](https://www.wearedevelopers.com/videos/254-tomorrow-s-cloud-data-platforms-fully-managed-database-as-a-service-dbaas) - [Introducing JSON Structure](https://www.wearedevelopers.com/videos/100219-introducing-json-structure) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Top 10 Java Libraries](https://www.wearedevelopers.com/magazine/364-top-10-java-libraries) - [Top Big Data Technologies That You Need to Know](https://www.wearedevelopers.com/magazine/108-top-big-data-technologies-that-you-need-to-know) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Making Data Warehouses Fast: A Developer’s Story](https://www.wearedevelopers.com/magazine/107-making-data-warehouses-fast-a-developer-s-story)
